Parade prop (5)
I believe the answer is:
strut
I believe this is a double definition.
'parade' is the first definition.
(I've seen this in another clue)
'prop' is the second definition.
(I've seen this before)
(Other definitions for strut that I've seen before include "Brace; swagger" , "Display arrogance" , "Swagger; bracing bar" , "Walk proudly like bantam-cock" , "Strengthening bar" .)
